Responsibilities Engineering a mdoel for the DME and VOR Navaids, work within a team to generate composite maps showing projected gaps in coverage at all sites in continental United States, work within a team to generate capacity planning for future based on these analyses plus flight test data corroboration. Accomplishments Simulation of satellite interference from cellular network builds (NOAA), and the simulation of Navaid (DME/VOR) Field Strength levels CONUS-wide (~1000 locations, five altitudes, 800,000 point files with LAT, LON, Altitude, Field Strength in dB uV per meter) (FAA). Generated graphics/data products and processed large data files using Matlab to quantify field strength of signal in space. Flight Test of multiple VOR sites, generated large data sets, final report delivered in support of VOR-MON contract. Skills Used Modeling and Simulation, Electromagnetic Field Strength Levels, Analysis of flight test data captured and comparison to simulation. Build a case supporting future navigation and backup systems to GNSS.

Performed RF coverage testing for 490/800 MHz Public Safety bands in subway tunnels in a system consisting of leaky coax, broadband distribution amplifiers, a distributed antenna system, and fiber optic back haul. Made measurements of up link and down link transmit/receive signal levels through a revenue generating train into the leaky coax, through the BDAs, and to the RADIO Operations Center via the fiber optic back haul. Researched potential interference via FCC ULS database, performed remediation efforts on RF Noise on the ICAD system in the 800 MHz Public Safety Band by measurement and setting of transmission level points, gains, and attenuator values to optimize the system for "unity gain".
